CLAMP FOR CUE-TIPS.

Specification of Letters Patent.

Patented Mar. 5, 1915.

Application filed January 22, 1914. Serial No. 813,795.

To all whom it may concern:

Be it known that I, HENRY BROBERG, a citizen of the United States,residing at WVarm Springs, in the county of Deer Lodge and State ofMontana, haveinvented certain new and useful Improvements in Clamps forCue-Tips, of which the following is a specifification.

This invention relates to a clamp which is intended to be used forholding the tip upon the ends of a one while the cement with which thetip is held in place is hardening.

One of the objects of the invention is to provide a clamp which is soconstructed that it will be securely held about a cue of any size, andto so construct tre clamp that it will not slip out of place while thecement is hardening.

Another object of the invention is to so construct the clamp that it maybe formed from a sheet metal blank which is bent to assume the propershape to form the complete clamp.

Another object of the invention is to so construct the clamp that whenthe turn screw is rotated to bring the cup into engagement with the onetip, the clamp will not be moved longitudinally upon the cue.

This invention is illustrated in the accom panying drawings whereinFigure l is a view in elevation showing the clamp applied to a cue withthe engaging cup shown in section; Fig. 2 is a transverse sectional viewtaken along the line 22 of Fig. 1; Fig. 3 is a view similar to Fig. 1with the clamp shown in longitudinal section; Fig. 4 is a view showingthe clamp and cue in elevation, the view being taken at right angles tothe view shown in Fig. 1.

The cue 10 is of the ordinary construction and is provided with a tip 11which is formed of any suitable material such as leather and connectedwith the end of the one by means of cement or the like. The clamp isformed from a blank of resilient sheet metal which is bent to form ahousing having a bridge 12 and side arms 13 and 14. In the center of thebridge 12 there is provided a bearing 15 provided with an opening fromthe edges of which there extends an internally threaded sleeve or collar16. This sleeve or collar 16 extends inwardly as shown at Fig. 3 andcarries a threaded stem or screw 17, the outer end of which is formedinto an enlarged head 18. This head 18 is provided so that the stem 17may be readily rotated and move the cup 19 into engagement with the onetip 11. This cup 19 is loosely mounted upon the reduced neck 20 of thestem 17 and is held in place by the head 21 which fits into a socketformed in the cup. It will thus be seen that after the cup has beenbrought into engagement with the cue tip, the cup will not rotate, butwill be pressed tightly against the cue tip when the stem is rotated.

The arms 13 and 14 have their free-end portions 22 brought toward eachother as shown at 28 and then carried parallel as clearly shown inFig. 1. The parallel end portions of the arms are curved to cause thearms to form jaws which will fit tightly about the one when the turnscrews 24 are tightened. The turn screws 24: pass through bearings 25and 26 which are formed in the wings 27 and 28 extending laterally fromthe jaws 22. The turn screws 24: are rotatably mounted in the bearings25 and pass through internally-threaded sleeves or collars 29 carried bythe bearings 26, and it will thus be seen that when the turn screws arerotated, the two jaws may be clamped tightly about the cue. The bearings26 are formed very similar to the bearings 15 and the bearings 25 arealso formed very similar to the bearings 15 with the exception that thebearings 25 are not provided with internally-threaded sleeves.

The operation of this device will be readily understood from aninspection of Figs. 1, 2, and 3. After the cue tip 11 has been placedagainst the end of the cue, the clamp will be placed upon the cue withthe cue extending between the jaws 22. The turn screws will then betightened to securely hold the clamp in place and the stem or turn screw17 will then be rotated to bring the cup 19 into engagement with the cuetip. This cue tip will be compressed as shown at Fig. 3 and held in thisposition until the cement has completed drying, at which time the clampcan be removed and the cue tip will be securely held in place. By havingthe cup concaved as shown in Figs. 1 and 3 the tip when compressed willbe prevented from moving transversely and will thus be held in thecenter of the one end and prevented from being secured to the one withone portion of the cup extending beyond the side of the cue.

I have thus provided a one tip clamp which can be easily and quickly putin place and which will securely hold the tip in place while the cementis drying. It should also be noted that by having this clamp formed ofresilient sheet metal, when the turn screws 24 are tightened, theresiliency will cause a binding engagement between the threads of theturn screw and sleeves 29 and thus prevent any danger of the turn screwsworking loose and permitting the clamp to move longitudinally toward theend of the cue and thus release the pressure upon the tip applied by theturn screw 17.

What is claimed:

A' clamp comprising a body portion formed from a blank of resilientmaterial bent intermediate its length to form a bridge having a threadedbearing, the end portions of said blank extending from said bridge toform arms extending in spaced relation and having their end portionsbent toward each other and then carried in spaced relation, the endportions of said arms being bent to form longitudinally extending jawsfor receiving a cue, side wings extending from said arms and providedwith bearings, one set of said last mentioned bearings being threaded,set screws passing through said last mentioned bearings for moving saidarms into clamping position, a set screw passing through said firstmentioned bearing, a tip engaging head carried by said set screw.

In testimony whereof I affix my signature in presence of two witnesses.

HENRY BROBERG.
